My invention pertains to methods-of fas' tening glass into metallic sash or sash having metallic edges and it is particularly adaptable to the fastening of glass into metal sash; of the same gneral'type as is used inthe" frame of window screens. My sash is useful in the formation of wlndows ofiany general typ e,'but by reason of the lightness, neatness and general economy of the construction, it 1s particularly valuable for movable glass structures such as wind guards for office Windows and the like. A particular adapta tio-ncontemplated by me is the provision of sash members to replace screen members in houses during the Winter time. The'solarium windows are generally of the casement type.

Slides for screens are'fastened'inside these windows on the sill and on the top and two horizontally slidable screens are placed within these guides. My construction makes it possible for the householder to replace 7 these screens with glass in the winter time thereby eliminating'drafts and conserving a heat in solariums in which frequently heating arrangements are inadequate.

It is an object of my invention llO'PBIlIlll] the installation of glass in light and inexpensive metallic frame structures. It is a fur ther object of .my invention to provide a positive fastening for the glass; one which will not permit it to rattle; one which is easily installed and provides a continuous and positive engagement for the glass;'- one which makes unnecessary the use of putty in" places where it can be seen, and where. 1t

may easily chip ofi. It is a further object of my invention to provide'an all-metal fas tening for glass in which the use of putty,

felt or calking is incidental and is not depended upon for a positive fastening. These and other objects of my invention I accomplish by that certain construction and an rangement of parts to be hereinafter more specifically pointed out and claimed.

Figure 5 illustrates the sprlng flCtlOILbf my glass fastener. V

Figure 6 shows the fastener fully installed; Metal sash or frames for Window screens v frame of the window screen ordinarily has a channel for a screen attachment member but in my construction I prefer to eliminate this channel and somewhat modify the form as will be described.

A piece of sheet metal is bent upon itself in the ordinary manner (see Figure 2) to form a square channel section 1, which is the body of the frame.

One side of the sheet metal forms a plain side of the frame which I'have designated as 2 and which is wider than the channel 1 and extends beyond it. The other side of the metal piece is bent so as to have an edge 3 lying along the back of the face '2 and the two metallic parts are conveniently spot welded together at intervals shown in Figures 2 and l. This spot welding draws the frame together and holds it rigid.

It will be understood that this construction gives to the sheet metal frame greater strength.

(iii

In my construction the side 2 is continued out further than the end of the piece '8 and a portion thereof is bent over to form a ridge as at 5. This ridge extends toward the back of the frame beyond thesurface of thepiece 3 and forms a shallow channel as will be understood. The construction so far described follows what has hitherto been done in the manufacture of metallic-framed window screens excepting that the piece 5 would be extended further in such construe: tions so as to provide between it and a channel 1 a deeper channel for the insertion'and.

fastening of the screen. Since in placing glass within my frame I do not have a problem'of fastening a flexible member within a channel, I stop the member short as shown so as to provide a bearing for the glass and only a shallow channel in which may be placed putty if desired.

My frame construction however differs further from the frame of a window screen in the slots which I provide for the accommodation of the tines of my fastening device. At intervals, adjacent the shoulder formed by the channel 1, I provide narrow slots 6, through which the tines may be inserted. These slots extend through the member 3. Inthe member I, Ijprovide av slot or. hole of the same width but of much greater length as at 7 sothat when a tine 1S inserted througn slot 6 and it is bent over it will lie within the hole 7 and will be flush with the surface of the side 2. 7

My screen fastening member consistsof a generally channel shaped piece of sheetmetal 8 in Figure 3. This metal should be springy in character and may conveniently be made of spring brass or bronze. It comprises a back portion 9, a rear side '10 and a front side 11. The shape of my channel is not rectangular. The side 10 further lies at less than a right angle to the back 9. The exact angle of the side 11 to the back 9 is not important though generally it will be made parallel to the side 10. At intervals tines 12 are fastened to the member 8. By reference to Figure 4- it will be seen that these tines are conveniently attached by being bent over at, their upper end as at 13 and spot welded, to the back 9 as at 1 1, though it will be clear that the tine may be otherwise attached if desired, or-cut out integral with the member 8. The tines 12 are narrow strips of sheet metal which will go through the slots 6. By reference to Figure 5, the method of use of my glass fastenerlwill be clear. A sheet of glass 15 is placed upon a frame. The glass will of course be cut to size and will rest upon the ridge 5, the end of it overlying the narrow channel formed by said ridge. My fastener 8 will be put in position adjacent the channel 1 with the side 10 abutting the shoulder thereof and the tines 12 extending through the slots 6. When first applied the fastener will be in the position: shown by the solid lines. l Vhen however the tine 12 is bent over so as to lie in theposition shown in the hole 7, the leverage exerted by bending over the tine will draw the fastener downinto position as shown in the dotted lines with the back 9 lying parallel with the frame member 2. i The side 10 abutting the shoulder of'the channel 1 and the side 11 bearing against the glass 15." t will now be seen that a rectangularrelationship of the parts of the fastenerhas been brought about-by the leverage, and that the spring- "iness of'the metal tending to cause the fastener to resume the shape shown in Figure 3 or in the solid lines in Figure 5 will cause the side 11 to bear against the glass with considerable force and the glass will be rigidly held between the members 5 and 11. Figure 6 shows more clearly the assembled relationship of the sash fastener and glass. It will be seen veryclearly in this View that when bent over as indicated, the end of the tine 12 will lie wholly within thehole in the side member 2 so as to be flush-with the sur-- face thereof. It will be obvious for this pur pose that tines 12 in my fastener will have been cut to a predetermined length.

" The finish placed upon the metal frame will now be applied and will cover both the surface 2 and the bent over end of the tine 12 so that upon this side of my frame the fastening means will be unobtrusive and may be entirely hidden. If desired, putty as at 16 may be placed in the channel of the frame and as at 17in the channel of my fastener, and I have found that when putty is so applied, I can achieve a construction in which water will not enter around the edges of the glass at all. Further, the putty is invisible to the observer excepting possibly through the glass and while I have shown in Figures 1, 5 and 6 a fastening member which is somewhat narrower than the channel of the frame, it will be obvious that I can make the channel and the fastening member of the same width if desired Further, it will be obvious that the putty is entirely closed from the air so that its life will be preserved and so that it cannot be chipped off or broken as in ordinary sash constructions in which putty is exposed. In my construction the putty has a calking function and is not at all relied upon to fasten glass in place.

'I have shown in Figure 1 a sash containing a single light of glass. It will be clear that when desired a sash may be made to contain one or more lights of glass by having members extending across the sash from side to side at intervals providing a shoulderequiva lent to that shown by channel 1, with a channel and a ridge 5 on either side thereof. Two or more lights of glass may then be placed in position and held there with the appropriate number of fasteners. I do not preferably bevel my fasteners but cut them of the proper length and form my corners as shown at 18 in Figure 1 because I find this gives a more attractive finishr Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is l 1.
